Big Bang effect

Could the Big Bang just be a focus point relative to our reference frame within an infinite space-time continuum?How can we have a beginning of the Universe with a Big Bang and still have causality the idea of cause precedes effect? The cause of the Big Bang would be part of the Universe and have to be explained!Does the electromagnetic spectrum being infinite and the infinities of human mathematics like π point towards an infinite Universe? Like Fred Hoyle’s Steady State Theory.The number of distinct photons or quanta of energy is ever increasing. If we go back in the course of time we must find fewer and fewer quanta, until we find all the energy of the Universe represented in a few quanta or even in a unique quantum fluctuation. But in atomic processes the idea of time or space are just statistical notions, they do not exist when applied to individual interactions between small numbers of quanta. If the Universe begun with a single quantum, the notions of time and space would fail to have any meaning at the beginning, they would only begin to have a sensible meaning when the original quantum had been divided into sufficient numbers of quanta. This suggest that the beginning of the Universe happened a little before the beginning of the process that forms time and space. Maybe an eternity before LOL!https://www.youtube.com/watch?v=C3EhViHYQsQ
